Description

Technical Field

[0001] This invention belongs to the field of water surface operation technology, specifically referring to a multi-functional robot for water surface operations. Background Technology

[0002] Currently, the cleanup of debris on the water surface mainly relies on manual dredging and traditional mechanical cleaning vessels. Manual dredging is inefficient, labor-intensive, and poses safety hazards. While traditional mechanical cleaning vessels improve efficiency to some extent, they still have the following technical shortcomings in practical applications: 1. Low efficiency of garbage collection and retrieval: Existing collection devices usually use rigid grabs or conveyor belts to directly scoop up garbage. When the grab opens, the water resistance is high, which leads to increased energy consumption, and garbage is not easy to enter the grab range. When closing, the captured garbage is easily leaked out due to water flow impact or garbage accumulation, resulting in unsatisfactory collection effect.

[0003] 2. High energy consumption and poor adaptability during conveying: To increase the amount of waste conveyed, baffles are often installed on conveyor belts. However, when the baffles move underwater with the conveyor belt, they are always in an extended state, generating significant underwater resistance. This not only increases the energy consumption of the drive motor but may also affect the stability of the vessel. Current technology lacks a structure that can automatically adjust the extension / retraction state of the baffles based on their position (above or below water).

[0004] 3. Lack of garbage fullness early warning mechanism or reliance on electronic components: Whether the garbage collection bin is full or not depends on manual visual inspection or the installation of electronic sensors. If manual inspection is not timely, garbage can easily overflow. Electronic sensors (such as infrared and ultrasonic sensors) are easily interfered with by garbage fragments and water vapor in humid and dirty water environments, resulting in false alarms or failures. They are unreliable and increase equipment costs and maintenance difficulty.

[0005] Therefore, developing a surface garbage cleaning robot capable of low-resistance garbage collection, adaptive energy-saving transportation, and reliable physical full-load alerts is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a multi-functional robot for surface operations. Through the opening and closing locking design of a one-way valve on the grasping frame, the contradiction between collection efficiency and water flow resistance is cleverly resolved, achieving highly efficient collection. Combined with the adaptive switching of the baffles on the conveyor belt between water ingress and outgress, energy consumption is significantly reduced. Furthermore, the purely mechanical full-load pop-up warning device completely avoids the risk of false alarms from electronic sensors in humid environments. The entire system is interconnected and interlocked, achieving a unified technical effect of low-resistance collection, energy-saving transmission, and reliable early warning through purely mechanical means.

[0007] The technical solution adopted by this invention is as follows: This invention provides a multi-functional robot for water surface operations, including a hull, a one-way valve-type grasping mechanism, a self-drag-reducing transmission device, and a collection and reminder device.

One side of the one-way valve is rotatably mounted in the gripping frame. An anti-rotation post is provided on the bottom wall of the convex upper part of the gripping frame.

A limiting post is provided on the bottom wall of the concave upper part of the gripping frame. The limiting post is close to the connecting rod to prevent the one-way valve from jamming due to excessive opening angle.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Highly efficient waste collection and gathering capability: This invention employs a linkage mechanism driven by a grabbing motor, comprising gears, support rods, connecting rods, and a grabbing frame. Combined with a one-way valve and an anti-rotation post on the grabbing frame, when the grabbing frame opens outwards, the one-way valve automatically opens under water resistance, allowing water flow and significantly reducing resistance during opening, thus guiding waste smoothly into the grabbing frame. When the grabbing frame closes inwards, the one-way valve automatically closes under the combined action of waste and water flow, and remains closed under the constraint of the anti-rotation post, effectively preventing waste leakage. This low-resistance, self-locking mechanical structure achieves highly efficient and reliable collection and gathering of surface waste. 2. Energy-saving and consumption-reducing adaptive conveying system: This invention features a retractable baffle on the conveyor belt, along with an extension limit plate and a retraction limit plate. When the baffle moves with the conveyor belt to the water inlet area, it automatically engages with the retraction limit groove through a wedge-shaped surface, thus retracting the baffle. This effectively reduces water resistance during water inlet and decreases the energy consumption of the drive motor, achieving energy saving. When the baffle moves to the water conveying area, it automatically engages with the extension limit groove, extending the baffle to ensure stable and efficient upward conveying of waste and prevent slippage. This ingenious structure is reliable and requires no additional power source. 3. Stable and reliable purely mechanical full-load reminder: This invention constructs a full-load reminder device using a purely mechanical structure including a movable frame, a moving plate, a trigger plate, a locking spring, a locking protrusion, and a spring plate. When the garbage accumulates to a certain weight, it drives the moving plate, causing the locking mechanism to disengage. Under the action of the compression spring, the reminder flag is automatically popped out. This design does not rely on any electronic sensors, avoiding interference from the harsh water environment. It has extremely high reliability and durability, and the structural cost is low. It can promptly and accurately remind staff to clean up, effectively preventing secondary pollution or equipment failure caused by overfilling. Attached Figure Description

[0027] In practical use, the hull 1 is moved to the water surface where the garbage is to be collected, and the grabbing motor 30 is started. The rotation of the grabbing motor 30 drives the gear 31 in grabbing component 28 to rotate. The rotation of gear 31 in grabbing component 28 drives the gear 31 in grabbing component 29 to rotate. The rotation of gear 31 in grabbing component 28 drives the support rod 34 to rotate. The rotation of support rod 34 drives the connecting rod 35 to rotate. The rotation of connecting rod 35 drives the grabbing frame 36 to first open outward and then close inward. When the grabbing frame 36 opens outward, under the action of water resistance, the one-way valve 37 rotates towards the concave surface of the grabbing frame 36, thereby allowing water to flow smoothly, reducing water resistance when opening, and facilitating the garbage to enter the grabbing area. Between the frames 36, when the grabbing frames 36 are pulled inward, under the combined action of water flow and garbage, the one-way valve 37 rotates towards the convex surface of the grabbing frames 36, and under the action of the anti-rotation column 38, the grabbing frames 36 are closed, effectively preventing garbage from flowing out, achieving the technical effect of efficient collection of garbage on the water surface. Next, the drive motor 24 is started, the drive motor 24 rotates and drives the drive roller 21 to rotate, the drive roller 21 rotates and drives the conveyor belt 6 to rotate, transporting the collected garbage. The rotation of the conveyor belt 6 drives the limiting fixing part 8 and the baffle 9 to rotate. The baffle 9 can effectively prevent the garbage on the conveyor belt 6 from sliding down. When the baffle 9 moves to the shrinking limiting plate 26, the wedge-shaped surface of the shrinking limiting plate 26... When the baffle 9 contacts the wedge-shaped surface of the extension limiting plate 26, the wedge-shaped surface of the baffle 9 moves upward along the wedge-shaped surface of the contraction limiting plate 26, causing the engaging protrusion 13 to disengage from the extension limiting groove 18 and engage with the contraction limiting groove 19, thus achieving the technical effect of contracting the baffle 9 and reducing the resistance of the baffle 9 when entering the water, achieving the technical effect of energy saving and consumption reduction. When the baffle 9 moves to the extension limiting plate 25, the wedge-shaped surface of the extension limiting plate 25 contacts the wedge-shaped surface of the baffle 9, and the wedge-shaped surface of the baffle 9 moves downward along the wedge-shaped surface of the extension limiting plate 25, causing the engaging protrusion 13 to disengage from the contraction limiting groove 19 and engage with the extension limiting groove 18, causing the baffle 9 to extend, so as to better collect and transport garbage. When the waste on conveyor belt 6 is transported to the highest point, it falls into the movable frame 41. As the amount of waste gradually increases, the waste pushes the moving plate 46 to move along the engaging moving groove 45. The movement of the moving plate 46 drives the support plate 47 to move, and the movement of the support plate 47 drives the trigger pin 48 to move. The movement of the trigger pin 48 pushes the trigger plate 58 to move. At this time, the locking spring 56 contracts, the locking protrusion 57 disengages from the engaging groove 59, and the spring plate 52 bounces up under the action of the compression spring 51. The upward movement of the spring plate 52 drives the reminder flag 53 to move up, and the reminder flag 53 is popped out from the reminder frame 50 to remind the staff to clean up the waste in time. The above is the specific working process of the present invention. This step can be repeated next time it is used.
